' Application filed December 16, 1922. Serial No. 607,370.

T all whom it may concern:

Be it known that I, WILLIAM: T. GARNEs, a citizen of the United States, residing at Kansas City, in the county of Jackson and 5 State of Missouri, have invented certain new and useful Improvements in Phonographs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification. My invention relates to phonographs and the object thereof is to provide a resonator or horn which projects the tones through the bottom of the machine case. Also to provide a mute or muffler and controlling mechanism therefor which can be positioned close to or spaced away from the resonator, or which can be used as a deflector to deflect the sound laterally when desired.

The features of my invention are hereinafter described and pointed out, and are illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of my improved resonator and mute mechanism with the casing of the machine outlined thereabout.

Figure 2 is a front view of the same. In these drawings A indicates the horn or resonator of a phonograph; B indicates the usual tone arm; B indicates a sound box of ordinary construction; and C indicates a turn table. I

The horn or resonator A is so formed that the bell portion A thereof will project the 0 sound therefrom through an opening in the bottom D of the case E of the machine. In order to reduce the volume of tone, as may be desired, I provide an adjustable mute or muffler plate F, which is suspended adjacent to the bell portion A of the resonator A by means of the side arms F. The upper ends of the arms F are pivoted to swinging arms G. These swinging arms Gr are secured upon a transverse shaft G by means of pins 9, see Fig. 2, said shaft G being mounted in suitable bearings H which are secured to the casingE of the machine, so that the swinging arms G will swing in unison and ,raise and lower each arm F simultaneously-g J indicates a swinging arm which is pivoted to bracket J secured to the casing E of the machine, the free end of which is connected with one of the swinging arms G by means of a link bar J 2 which is pivoted on the arms J and G. Pivoted on the arm'J is a lever K to the lower end of which is pivoted a link bar L, the opposite ends thereof being pivoted to one of the bars F, so that by means of the lever K the swinging arms G can be operated to lower the muflier plate F as shown by broken lines f and to swing said plate laterally as shown by broken lines f f in Fig. 1. To counterbalance the mufiier mechanism hereinbefore' described, I provide a weight M see Fig. 2 7 from which a cord M extends on a pulley M and thence down to one of the swinging arms G to which said cord is secured. I also provide a tubular guide N for the weight M, the upper end of which is secured to the upper board of the machine frame E by means of an ear m, the pulley M being pivoted in the upper end of said guide.

From the foregoing description it will be obvious that the sound will be thrown downwardly by the resonator and that the mufiier plate F can be spaced with relation to the resonator as may be desired, andthat by means of the counter weight it will be maintained in the desired position. Also that it can be swung laterally to deflect the sound toward the front or rear as may be desired.

Having thus shown and described my invention so as to enable others to utilize the same I do not desire to be limited to the exact construction of mechanism shown and described, as many modifications can be made therein without departing from the scope of my invention, therefore what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus of the class described, sound reproducing mechanism, a case enclosing the same, a resonator, a muffler plate, means to move said plate away from and 1 toward said resonator, and means to swing said'plate laterally.

2. In an apparatus of the class described, sound reproducing mechanism, a case enclosing the same, a resonator, a muffler plate, 105 arms on said plate at opposite sides of said resonator, swinging bars pivoted to said case and to said arms, another swinging bar pivoted to said case, a link connecting the free end of said last mentioned bar and the 110 first mentioned bar, a hand operate ad lever pivoted to the last mentioned bar, a link connecting said lever with said arms, and means to counter balance said mufiier plate and operating mechanism.

3. In an apparatus of the class described, sound reproducing mechanism, a case enc10s ing the same, a resonator, a muflier plate,

' arms secured on said plate at opposite sides said resonator, vertically swinging bars pivoted to said case and'to said aftn'sflneans to counter-balance said inufiier plate and bars, and lever and link mechanism to depress said muflier plate and simultaneously cause the same to swing laterally.

In testimony whereof I affix my signature.
